stringz creates a char*
but you need a wchar*
std.utf.toUTF16z or toUTFz can do that for you, though if your
string is already a wstring, then you can also just concatenate
'\0' to it. the big advantage toUTF16z is that it will also
convert strings of other character types rather than just
wstrings. So, you can write your program using proper UTF-8
strings and then only convert to UTF-16 for the Windows stuff
when you have to.

Is there a reason we cannot implement toStringz like:
immutable(TChar)* toStringz(TChar = char)(scope const(TChar)[] s)
@trusted pure nothrow;
// Couldn't find a way to get the char type of a string, so
couldn't make the following generic:
immutable(char)* toStringz(return scope string s) @trusted pure
nothrow;
immutable(wchar)* toStringz(return scope wstring s) @trusted pure
nothrow;
immutable(dchar)* toStringz(return scope dstring s) @trusted pure
nothrow;
